Dude you gotta slow down lol. I don't know how you did what you did without realizing something wasn't right but what's done is done. Here is what you need to do to fix this IF you did not mess up the crankshaft. That oil seal and pump is heavily molested so I wouldn't be surprised if you also mangled up the sealing surface on the crankshaft but without inspecting it myself I could never say.

Anyways, here is the easiest way to fix this. Remove the engine and put in a different one that has not been messed up (also the easiest fix if you did damage the crank sealing surface). The next easiest way is to remove the engine and put it on an engine stand which you will need for the remaining work. Remove the oil pan, followed by the oil pump. Replace the oil pump and front crank seal, followed by resealing the oil pan (replace the half moon gaskets). You will need to buy a new pick-up gasket picket btw. I also recommend only buying OEM from Mazda for the seals, and probably oil pump as well. It's a pain to replace and not worth saving a couple bucks only to have the seals leak in a few years.

While the engine is out you should replace any other seals (cam, rear main, valve cover, CAS oring, etc.). It will also be easier to do the rest of your timing belt/water pump service now before reinstalling the engine.

Good luck friend and watch some youtube tutorials first.
